You can inform the Range Superintendent about the payment being made by the challan for F.Y.2015-16. The Service Tax Challan has no period mentioned, so it can be used for any payment and adjusted against the same. However, the interest for late payment too has to be made, if necessary by a separate challan and the same too should be intimated to the Range superintendent.
Claiming refund after paying the outstanding dues is also an option - but the application for refund should be made within one year of the payment and it is very, very difficult / almost impossible to get a refund from the Central Excise / Service Tax Department.

There is no way it can be revised. Has your client shown a lower Turnover than in the accounts or was the correct turnover shown and a mistake in tax calculation.

The tax on the short reported Turnover be adjusted from payment of FY 2015-16. Pay the interest for the delayed period and intimate the Range Superintendent of the mistake and rectification by a duly recipted letter.
